How to overcome a creative block ?

I’ve noticed something strange about myself, as soon as I sit down at my desk at home, my inspiration just disappears, the walls in the room are plain, my eyes keep landing on an empty corner, and my thoughts start drifting away, I used to think minimalism helped with concentration, but now I realize I’m seriously lacking visual stimulation, I want to transform my workspace somehow and add something that would wake up my brain, but without making the room look like a teenager’s bedroom full of magazine posters, has anyone tried using interior artwork with deeper meaning or quotes, does it actually help you get into the right mindset, or is it just another marketing trick from interior designers?
